Couldn't print the version on the failed box. I had run a force install of DBI earlier, so besides renaming those files, I had to restore some files under vendor. But once I did that, then I was able to print the version.
Then I went and tried to upgrade DBD::ODBC, but got a similar failure, Can't find boot_DBD__ODBC. I didn't force this, so didn't need to back anything out.
